广西桂南、桂西地区,近年试种紫云英、苕子,初步获得成功,并广泛用作水稻基肥,从而为该地区开辟肥源,进一步发展农业生产,开创了有效而可行的途径。1962和1963年,本所连续进行了水稻的肥料试验,主要是以紫云英、苕子压青与化肥、农家肥及犁翻晒冬田(以下简称犁霜)的肥效对比试验,探索不同压青量对早晚稻的增产效果,目的在于提供一些资料,以作今后合理利用绿肥参考。
Guangxi Guinan and GuiXi areas, in recent years, the trial of asparagus, razor clam, initial success, and is widely used as rice base fertilizer, thus opening up fertilizer sources in this area and further developing agricultural production, creating an effective and feasible way. In 1962 and 1963, we conducted a series of fertilizer experiments on rice. The experiment mainly focused on the comparison of fertilization efficiency between Chinese milk vetch, clams pressed green with fertilizers, farmyard manure and plowed and sun-dried winter fields (hereinafter referred to as plow frost) The effect of green yield on the yield of early and late rice is to provide some information for rational utilization of green manure reference in the future.
